I tested 80% ceramic tint on my 2018 Honda CRV. The data won't format correctly, but here it is. NO tint on windshield! Front and rear sides and rear windows had factory colored window glass before tinting. Rear window didn't get the 80% applied. Big difference on the inside temperature even in the full sun, but didn't measure IR (no device to measure with). Interesting that on subsequent measurements of the windshield, the result were always zero for the inside UV.
